Title: Spherical high pressure gas-holder - with inner inflatable thermoplastic bladder for corrosion protection
Inventor: KRUEGER HORST DIPL CHEM DR
IPC: F17C1/10
Filed: 1976-07-27
Abstract: A spherical gas holder for high-press. coke oven gas consists of a rigid metal sphere with an inner inflatable sheath which protects the metal against chemical attack by chemicals in the gas liquor. The sheath is a gastight ballon, suspended from a manhole which transmits the gas press. to the metal sphere and can move relative to the latter. This prevents attack by hydrocyanic acid without expensive gas drying or purification units. The sheath resists temp. and press. fluctuations and does not flake off like inside coats of paint. A welded hollow steel sheet sphere includes a sheath made of thermoplastic foil, reinforced by fabric, which is clamped by a ring at the tom rim of a manhole. Additional hangers suspend the sheath when not inflated. Only the dome, lid and ring are made of alloy steel. The bottom of the sheath can form a reinforced disc to leave a small space for leakage gas liquor and for ultrasonic flaw detection surfaces. The outside of the sheath has pref. raised bosses on which it can slide relative to the wall.

Title: Brake system responsive to rear axle loading - has front brake control valve with valve in by=pass line held closed by rear brake pressure
Inventor: MUELLER JAROSLAV
IPC: B60T8/26
Filed: 1976-08-07
Abstract: The front and rear brakes are controlled w.r.t. the rear axle loading by a special valve in the rear axle brake line, and by a separate control valve (10) in the front axle brake line. The control valve operates in relation to the modulated pressure of the rear brakes. A bypass line (11) to the front axle valve is fitted with a simple valve (12) held closed by the rear brake pressure so that if the rear brakes fail then the full braking force is available for the front brakes. The system provides a failsafe interlock so that the vehicle can be braked safely while retaining the load sensitive control on both axles.

Title: Resiliently supported sieve base - has grooves fitting onto headed resilient support members permitting bending for high rigidity
Inventor: SCHMIDT GERHARD
IPC: B07B1/46
Filed: 1977-02-15

Patent DE-2719402-A1 (DE)
Inventor: RATHERT HORST ING GRAD
IPC: B42C5/04
Filed: 1977-04-30
Abstract: The sheets or book sections compiled to form blocks (1) and held in carrier tongs (2) are passed over cutting tools (3, 4) to remove the spine and joined by adhesive bonding to form a block. In this process, the spine of the block is provided with approximately sawtooth incisions (7) oriented transversely to the direction of advance of the block. These sawtooth incisions are then filled with an adhesive which, after hardening, firmly holds the sheets or book sections. The cutting tools substantially consist of a rotating cutting disc (3), on the periphery of which a number of cutting wedges (4) are arranged. These cutting wedges are steel profiles whose cutting part (15a) is shaped correspondingly to the sawtooth contour of the spine incisions. The distance between the individual cutting wedges on the cutting disc, the disc advance and the speed of rotation of the disc are so selected that consecutive profile incisions can be made in the block spine. <IMAGE>

Title: Fairground swing drive system - includes friction wheels driven by hydraulic motor and in contact during part of swing
IPC: A63G9/16
Filed: 1978-03-17
Abstract: The drive system for a large swing for e.g. a fairground, uses motor driven drive wheels which for at lest a part of each swinging movement have a friction contact with the swing basket. The drive wheels are driven by at least one hydraulic oil motor which during the beginning of the drive provides a special pre-determined revolution for each swing movement. During the contact period pressure devices force the drive wheel with a power which remains the same against the basket. In addition there is a pressure regulator controlling the revolutions of the drive wheels by limiting the oil pressure.
